Trailer wiring connections can often fall victim to rust and corrosion, but with Pollak's heavy-duty, 7-pole trailer wiring connector, you won’t have to worry. It's coated with dielectric, non-conducting grease, protecting against any moisture ingress and ensuring an uninterrupted electrical connection for years to come.
Connecting and unplugging your trailer wiring shouldn't be a struggle. With the intelligently designed jumbo finger-pull grips, this connector makes insertion and removal incredibly easy, even in tight spaces. Just grab, pull, and you’re set without putting a strain on your hands.
When you're dealing with multiple vehicles and trailers, compatibility is key. This trailer wiring connector meets and exceeds all SAE J560 standards, making it interchangeable with all competitive American Trucking Associations (ATA) types and ensuring it works seamlessly across various setups.
Towing setups can vary, and so do the wiring gauges used. That's why the Pollak connector is designed to accommodate a wide range of wire gauges, from #16 for most typical uses to #8 for heavy-duty applications like ground wires. You won’t need to worry about mismatched wiring when connecting your trailer.
Designed for those who need robust reliability, this connector features round, floating, solid brass pins and a zinc die-cast housing. It's built to minimize voltage drop and resist wear and tear, making it solid and literally indestructible, just like our satisfied customer JH said.
Weather conditions shouldn’t dictate when you can use your trailer setup. Featuring a high-impact ABS thermoplastic interior, this connector withstands tough environmental conditions. Whether you’re working under the blazing sun or in freezing temperatures, expect dependable performance every time.
Does not fit Pollak Cable Guard (PK11763). Use Pollak HD, 7-Pole Round Pin Connector w/Cable Guard (PK11702).
Excellent quality.
Just what I wanted, with fast shipping.
Great connecter, high quality part, great documintation
Just what I was looking for. Good quality, fast service, and reasonable pricing. Thanks.
Great ProductsThe products that I purchased were all great, and the help info tab was very helpful.
Good solid connector, but I didn't realize that it could be ordered with the spring to protect the wires from sharp bends, part #PK11702, which I'll order next time.
Great Purchase experiance. Product was as presented (Heavy Duty)
Prompt Shipping and good follow up.
Easy to install
I was very pleased with this connector. It is robust and of high quality for its cost. I'd highly recommend it.
Product was as expected.
The plugs did what they were supposed to do, and the customer service was excellent.
I searched locally for a 7-pin trailer plug without finding any round-pin styles only flat blade. I searched online and found this plug.
This plug is very well made, easy to connect wires to and fits the socket on my Kubota tractor.
Also, it was in stock and shipped much faster than I expected, which I greatly appreciated.

I am very pleased with the product. It is working great on my Kubota tractor.
Excellent quality
Shipping was fast. Great service
If you have any agricultural equipment, this is the easiest way to adapt the normal automotive style connectors to your vehicles and equipment. Great product, and as usual, ETrailer.com has the best price and least expensive way of shipping it to you.

Still great,
The only place who has this old plug
The way the connector comes apart & goes back together is very sensible. The terminal connections can accommodate large wires - up to 12 gauge on all except for 1 that can go up to 10 gauge as far as I can remember. They could possibly handle larger but I didn't check since I didn't need the wires that large. They're labeled for standard 7-way trailer wire colors, which is useful for most people but I couldn't go by it. Mine was a custom application. If a spring strain relief came with it that would be awesome but I wouldn't expect it for the price I paid. Hope that info helps.
I have a 1993 ford e150 with a factory I installed trailer connector round pin. I couldn't find a 7 to 4 match anywhere. Then I saw this pk11700 adapter and it worked great. Plus I have extra connectors now to add other lights. Great product thx
the connector is "as advertised" (which is refreshing) it needs some sort of protective cover of the wires as they enter the plug, but maybe it is available and i didn't see to order it. I would buy it again.
The cable end plug arrived on the exact estimated date I was given on the day of ordering. Wiring it is very simple. There is a screw for each terminal opening. Use a small phillips screwdriver to thread the screw out, insert the wire, and then tighten the screw.
A retention clamp is an integral part of the plug. Again it is a simple matter of turning a screw to open it and tighten it back down again. The plug is well made and should last a long time. It is exactly the replacement part I was looking for.
I will come back to etrailer.com when I need related items. I highly recommend.
Just reviewed the truck receiver half of this product - same deal. Nice heavy parts - little plastic. Nice big round brass contact pins; due to the fact that these parts are cast, there is little chance of water/dirt/condensation working into the wire contacts. Locks in tight with the receiver. All in all, a good purchase.
Haven't wired up the connector yet. Would have been nice if the standard wiring diagram used through out the USA would have been included. Then the trailer would be wired correctly to any vehicle that was using it. Mine didn't have the trailer brake or back up lite shown.
It is very refreshing in this age of Internet shopping to find a site that provides good product information, competitive pricing and great customer before and after the purchase. Product was exactly what the product info on the site stated. Appreciate the good service and will definitely use etrailer.com for future needs.
Thanks.
For me, and probably you, etrailer.com is a great place to shop/buy quality products. They give great follow up after ordering and fast shipping @ a fair price. I believe their service & pricing is unbeatable. I do shop for bargains & etrailer is @ the top of my list.

Still working fine. My application was just a replacement for a damaged plug.
